The Xerox Alto, the computer that introduced us to the Graphical User Interface (GUI) and forever aliented Command-Line Interface (CLI) programmers everywhere, has reached the ripe old age of 30. So, Vintage and the Computer History Museum is celebrating this weekend it in grand style by having a panel of past and present Xerox PARC luminaries speak about the development of the Alto. They are also featuring a line-up of classic (and working) Xerox machines. Jef Raskin will speak on the second day of the event, so if you live in the Bay Area, don't miss it this weekend!
